PIC-to-PIC experiment at 130Gb/s based on a monolithic transmitter using switching of prefixed optical phases and a monolithic coherent receiver

We send data from a monolithic 32.5Gbaud QPSK transmitter based on switching of prefixed phases, to a 43GHz-bandwidth integrated receiver. We demonstrate 130Gb/s bit-rate per wavelength, more than twice the rate of previous PIC-to-PIC experiments.
